Although GBP/AUD has been spiking in the recent past from the lows of 1.6720 to the current 1.7189 levels, the bears of this pair can load up shorts in underlying pair with longer tenors to arrest major downtrend as the selling momentum is intensified by leading oscillators with mammoth volumes.

So it is advisable to initiate Diagonal Credit Put Spread (DCPS) in order to tackle both short-term upswings and major downtrend.

Usually, pondering over the option sensitivity tool, IVs and OTC indications these puzzling could be optimally tackled and attained the trade or investment objectives via theta options of shorter tenors.

As we expect the retest of multi-months lows of 1.6720 in the weeks to come amid any abrupt upswings.

For the ease of understanding, we’ve just considered this option strategy with shorts in 1W (1%) ITM put with positive theta or closer to zero while buying 1M (0.5%) OTM put option; the strategy could be executed at the net credit.

For an instance, as we know theta measures time decay in your options premium value per day which mean as shown in the diagram the premiums on short leg today is worth $2123 and theta is $55 then over every time break, all else been equal, the option premium should be waning out to $2068. This would be the case even when underlying spot never goes up but remains in sideways.

Option sellers can reap the benefits of a high Theta near expiry by selling short-dated ATM options with the expectation of little to almost no market movement.

For ITM and OTM options as the time to expiry draws nearer, Theta lowers and decreases.

Well, in above case of diagonal credit put spreads, the strategy could be constructed at the net credit, the short leg would be absolutely at profits when underlying spot remains either at strikes chosen or at higher than strikes on the expiration of short side.

Thereafter, the major trend prolongs to evidence further slumps, narrowed OTM longs would mitigate downside risks on the other hand as the holder of such option would be having right sell at predetermined strikes.
